centos7下安裝redis日常筆記
延續之前的centos7下開發環境搭建，這次安裝redis，本以為redis這種開發常用軟體官方的源裡直接有，但是執行結果是找不到。去官網看看，也沒有yum安裝的支援。再去網上找找，發現都是用的epel源，於是安裝源後直接安裝。
yum install epel-release
安裝完成之後查詢下有沒有redis
[[email protected] dev.hzm.com]# yum search redis

yum install redis
安裝完成後修改配置檔案/etc/redis.conf,修改繫結埠，密碼等，如果不需要也可以不修改。至於bind配置，有很多人理解是錯誤的，那些理解為讓其他機器訪問的ip白名單是錯誤的，他們肯定沒有跑起來過，在那瞎說。bind的作用是讓redis知道用本機的哪個網路介面，比如這臺機器有兩個網絡卡，一個通外網，一個通內網，兩個ip，顯然監聽外網的請求是不安全的。
修改埠，預設6379
# Accept connections on the specified port, default is 6379 (IANA #815344).
# If port 0 is specified Redis will not listen on a TCP socket.
port 6379
修改密碼
# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second against a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.
#
# requirepass foobared
requirepass 123456
開啟服務
systemctl start redis.service
檢視日誌cat /var/log/redis/redis.log沒有問題
